Dear hackers,

I found that such a statement would get 0 in PL/pgSQL.

PREPARE smt_del(int) AS DELETE FROM t1;
EXECUTE 'EXECUTE smt_del(100)';
GET DIAGNOSTICS j = ROW_COUNT;

In fact, this is a problem with SPI, it does not support getting result
of the EXECUTE command. I made a little enhancement. Support for the
number of rows processed when executing INSERT/UPDATE/DELETE statements
dynamically.

Is there some use case for support this feature?

Regards

Pavel
